I was reading over the “The Bulk-Building Workout” and I am a little confused about the format of the workout. For example for Day 1 it lists as A1 Squats, then A2 Pullovers, then B Dynamic Lunges, and C Single Leg Squats.
Now am I supposed to superset the squats and the pullovers? Or is there any reason why it is A1 and A2? I am a little confused about that. Any advice would be appreciated.
